DAVID BALDWIN PIERSON, 0F HARTFORD, CONNECTICUT; MARY N. PIERSON ADMINISTRATRIX OF SAID DAVID BALDWIN PIERSON, DECEASED.

MILK-BOTTLE CLOSURE AND STOPPER-EXTRACTOR.

Application filed August 15, 1911.

To all whom it may concern Be it known'that I, DAVID BALDWIN PIER- SON, a citizen of the United States of America, residing at Hartford, in the county of Hartford and State of Connecticut, have invented new and useful Improvements in Milk-Bottle Closures and Stopper-Extractors, of which the following is a specificat on, reference being had to the accompanying drawings and letters of reference marked thereon.

The object of my invention is to provide a simple, inexpensive, sanitary and ad1ustable device for employment with milk bottles with which the usual paper or cardboard stopper may be conveniently removed and the closure device substituted, thus hermetically sealing the bottle, and I accomplish the objects of my invention by the construction herein shown.

In the accompanying drawings, in which like letters of reference indicate like parts, Figure l is a side elevation of my device; Fig. 2, aside View in section; Fig. 3, a side view with the parts detached, and Fig. 4, a plan view.

In detail, a indicates the lower body portion of the device, b-the upper body portion, 0 the threaded member by means of which thetwo are connected, at a raised surface, 6 an expansible packing rin and f a hook or pin for the removal 0 the pasteboard stopper.

The construction of my device will be readily understood on reference to the draw ings.

The lower body portion of the device is provided with a downwardlyprojecting hook f for engagement with the ordinary paper stopper employed in bottles and by which the same may be readily removed. The lower body portion is provided also with an upwardly-projecting threaded member o and with a raised portion d, the same being raised, however, a distance less than the thickness of the packing ring. The up per body portion b is provided with a threaded recess to receive the threaded member 0 of the lower portion, and the packing ring 6 is clamped between the por tions of the upper and lower body por Specification of Letters Patent.

openin s of slightly differing diameters by the dii'erence in the extent of com ression applied to it by screwing the two bo y members together more or less tightly, so that if it be found that the ring 1s loose when applied to a bottle, the two members may be screwed more tightly together, thus compressing the packing ring, causing it to expand slightly, thus increasing its diameter and causing it to fit more tightly in the bottle opening. The upper body member is provided with a convenient knob or handle.

It will readily be seen. that inmaking the device readily separable, that it may be easily cleansed by separating the parts,

washing them, and replacing them, so that all danger of contagion resulting from particles of food lodging in crevices of the device may be readily avoided, and that the device may be conveniently separated, cleansed, and reassembled.

Having, therefore, described my invention, what I claim and desire to secure by Letters Patent, is-

A bottle closure of the character specified, comprising superposed upper and. lower disk-like body members, the latter of which is provided upon its upper face with a central raised portion and with an 11 standing threaded projection located centra 1y of the same, the upper body member having a threaded recess opening through the center of its under face to receive said projection, a handle provided upon said upper body member, and a yielding packing ring of greater diameter than said members en- DAVID BALDWIN PIERSON.
